*aeh* whats that '?' before N:... ?
Is this an error of your mailclient or is it indeed in your command?
Can you attach the script (to avoid error due copy and paste)?

Well maybe the magic '?' in the command is _really_ in the command.
This error indicates that you called:
rrdtool update ... _AND_ then ?N:$mail_input:$...

(These are two errors. "expected timestamp" from rrdtool and "18461263: not=
found" from the shell).

[... snipp ...]
See the mystic '?' again !
I guess thats really the reason your commands failed.
